The compressor going off and on is being controlled by a pressure switch that is there to protect your compressor. Too little freon will hurt the compressor, so will too much. The pressure switch will stop the compressor from running when there is either too much pressure or not enough. I never said that all you need is freon. If your freon is low, it got out somehow and that leak needs to be fixed. However, many times a freon leak is very slow and can't easily be found. So, they put a UV dye in and when it leaks out, it'll leave a visual indication of where the leak is.

There is nothing more frightening than ignorance in action.

REWARD EXCELLENCE!
